Well thanks for all the great replies! This Lion battery has been very impressive. I put in a victron bluetooth smart shunt and have done several tests of my own. My alternator alone puts in 90 amps even when the battery is at about 70 percent. I disabled that by removing the 250 mega fuse by the chassis battery. I was concerned about over taxing the alternator. That fuse is super easy to get to so if I want to use the alternator it very easy to put it back in.
I also did get that powermax lk55 online for 119.00. I adjusted it to 14.6 which is what LION recommends. If you take the cover off there is second dial and you can adjust the current. I have found that the LION can take so much current so fast the most I can get is 30 to 35 amps when set at 14.6 Two problems when you turn the voltage over 14.6 one is the over current protection shuts off the power in the pm lk55 and if you set it higher than 14.6 the LION BMS shuts it down. Now this only happens at the top of the charge but I feel better running this at 14.6 so the BMD is not always kicking in. I took the cover off the converter and modified it to fit in my wfco 8900 series. I actually bought two of the pm lk55's because the price was right. I also like the idea the converter is not running at its top limits maybe it will last longer.
Thanks again!
